 Sodium benzoate is a preservative used in pharmaceutical oral liquid, sour to prevent deterioration and prolong shelf-life results, the amount of human liver would be too much harm, and even cancer.

This paper describes the benzoic acid and sodium benzoate physical and chemical properties, corrosion mechanism of toxicity and its detoxification mechanism in the human body, as well as foreign use of these two preservatives, designed to explore the possibility of benzoic acid and sodium benzoate Add meat used to provide reference.
